Ultrasound Assisted Assay for Toxins in Blood. SBIR 90.I (A90-180)

摘要

Work was carried out to determine the feasibility for a spectroscopic analysis ofsaxitoxin in whole blood samples. Modifications of standard chemical assays were to be used in conjunction with TRA's ultrasonic blood separation technology to form an analytical detection system that is suitable for field use by minimally trained personnel. The chemical assay method was successfully to generate a fluorescent saxitoxin derivative using solid oxidants in a stable dry formulation. Direct detection of low levels of this analyte in plasma was precluded by interference from the plasma matrix.
